Feature: SkillService uncovered code paths
As a developer maintaining the SkillService
I want comprehensive test coverage for defensive guards, exception
handling in database persistence, and the update-persist path
So that edge cases and failure modes are verified
#
# add_skill: None config guard (line 95)
#
@ssc_none_config
Scenario: add_skill raises ValueError when config is None
Given a skill service without persistence
When I call add_skill with a None config
Then a ssc ValueError should be raised with message "config cannot be None"
# ────────────────────────────────────────────────────────
# _load_from_db: early return when repo is None (line 278)
# ────────────────────────────────────────────────────────
@ssc_load_no_repo
Scenario: _load_from_db returns immediately when no repo is set
Given a skill service without persistence
When I explicitly call _load_from_db
Then the skills cache should remain empty
And no ssc error should be raised
# ────────────────────────────────────────────────────────
# _load_from_db: exception handling (lines 287-288)
# ────────────────────────────────────────────────────────
@ssc_load_db_error
Scenario: _load_from_db logs warning when list_all raises an exception
Given a mock skill repo that raises on list_all
When I create a skill service with the failing repo
Then the skills cache should remain empty
And a warning about failed database load should be logged
# ────────────────────────────────────────────────────────
# _persist_skill: update path (line 298)
# ────────────────────────────────────────────────────────
@ssc_persist_update
Scenario: Updating an existing skill calls repo.update instead of repo.create
Given a skill service with a mock repo and session factory
And I add a skill "local/update-target" via config
When I update the skill "local/update-target" via add_skill with update flag
Then the mock repo update method should have been called
And the mock repo create method should have been called once
# ────────────────────────────────────────────────────────
# _persist_skill: exception handling on create (lines 300-304)
# ────────────────────────────────────────────────────────
@ssc_persist_create_error
Scenario: _persist_skill logs warning when repo.create raises
Given a mock skill repo that raises on create
And a skill service with the failing-create repo
When I add a skill "local/fail-persist" via config ignoring persist errors
Then the skill should still be in the in-memory cache
And a warning about failed persist should be logged
# ────────────────────────────────────────────────────────
# _persist_skill: exception handling on update (lines 300-304)
# ────────────────────────────────────────────────────────
@ssc_persist_update_error
Scenario: _persist_skill logs warning when repo.update raises
Given a mock skill repo that raises on update
And a skill service with the failing-update repo
And I add a new skill "local/upd-fail" to the service
When I update skill "local/upd-fail" with update flag ignoring persist errors
Then the updated skill should be in the in-memory cache
And a warning about failed persist on update should be logged
# ────────────────────────────────────────────────────────
# _delete_skill_from_db: exception handling (lines 314-318)
# ────────────────────────────────────────────────────────
@ssc_delete_db_error
Scenario: _delete_skill_from_db logs warning when repo.delete raises
Given a mock skill repo that raises on delete
And a skill service with the failing-delete repo
And I add a skill "local/del-fail" to the failing-delete service
When I remove skill "local/del-fail" from the service
Then the skill should be removed from the in-memory cache
And a warning about failed database delete should be logged
# ────────────────────────────────────────────────────────
# _commit: early return when no session_factory (line 324)
# ────────────────────────────────────────────────────────
@ssc_commit_no_session
Scenario: _commit returns early when session_factory is None
Given a skill service with a mock repo but no session factory
When I add a skill "local/no-session" via config on the no-session service
Then the skill should be in the no-session service cache
And no ssc error should be raised
# ────────────────────────────────────────────────────────
# _commit: exception handling (lines 328-329)
# ────────────────────────────────────────────────────────
@ssc_commit_error
Scenario: _commit logs warning when session.commit raises
Given a mock session factory that raises on commit
And a skill service with a mock repo and the failing session factory
When I add a skill "local/commit-fail" via config on the failing-commit service
Then the skill should be in the failing-commit service cache
And a warning about failed session commit should be logged
